Numerical analysis of physical barriers to mitigate the gas tank explosion effects using computational fluid dynamics

Abstract In many urban buildings, there is the presence of gas central storage, which contain pressurized tanks. One main risks in these places an explosion, may or not followed by fire. general, shock wave formed this phenomenon disastrous and can cause material damage even fatalities. Recent research has contributed to understanding protective systems against phenomenon; however, it necessary advance developing protection devices for storage. From perspective, implementation plan order mitigate harmful effects explosions are essential raise safety level construction. Physical barriers appropriate solutions especially where impossible bury reservoirs. addition potential reduce back pressure levels, walls, when properly designed, also prevent spread debris from explosion. Another kind barrier that influences propagation close ground ditches, whose function related absorption redirection energy. Understanding positioning, geometry, overpressure attenuation physical safer more reliable projects. This article aims study buildings with The was developed numerically using Autodyn software. program a tool based on computational fluid dynamics (CFD). capacity proposed types regarding mitigation incident overpressures evaluated qualitatively quantitatively.
